Quality Standard
Take a look at the materials. The aluminum profiles, thickness, strength and oxide film used for high-quality aluminum alloy doors and windows should comply with relevant national standards. The wall thickness should be above 2.0 mm, the tensile strength should reach 157 Newtons per square millimeter, the yield strength should reach 108 Newtons per square millimeter, and the oxide film thickness should reach 10 microns. If the above standards are not met, the aluminum alloy doors and windows are of inferior quality and cannot be used.
Second, look at processing. High-quality aluminum alloy doors and windows, fine processing, exquisite installation, good sealing performance, and easy opening and closing. Inferior aluminum alloy doors and windows, blindly select the series and specifications of aluminum profiles, shoddy processing, use saw cutting instead of milling, do not install as required, poor sealing performance, inconvenient switching, not only air leaks and rain and glass bursts, but also Under strong wind and external force, it is easy to scrape or knock down the sliding part or the glass, causing damage to people.
Three look at the price. In general, the price of high-quality aluminum alloy doors and windows is about 30% higher than that of inferior aluminum alloy doors and windows due to the high production cost. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm, the tensile strength and yield strength are much lower than the relevant national standards, and it is very unsafe to use. In addition, there are many self-employed people who process aluminum alloy doors and windows, and they do not understand the structural characteristics and performance of aluminum alloy doors and windows. In order to reduce costs and cut corners, use shoddy products, and the hidden dangers of products are relatively large, so it is generally not suitable to use. It is best to choose products from regular aluminum alloy doors and windows manufacturers. Here is a special point: the national standard profile thickness is 1.4mm. If the supplier chooses a material with a wall thickness of 1.2mm or 1.0mm or even thinner, it is a product that does not meet the standard. Please pay attention when purchasing .
Four look at the material
There are 6 main aspects for reference in materials:
⒈Thickness: There are 70 series and 90 series of aluminum alloy sliding doors and windows, and 70 series can be used for aluminum alloy sliding doors inside the house. The aluminum alloy series number indicates the thickness of the door frame in millimeters of the structural dimension. Common aluminum alloy sliding windows include 55 series, 60 series, 70 series and 90 series. The selection should be determined according to the size of the window hole and the local wind pressure value. The aluminum alloy sliding window used as a closed balcony should not be less than 70 series.
⒉ Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing, the profile can be bent moderately, and it should be able to return to its original shape after letting go.
3. Chromaticity: The same aluminum alloy profile should have the same color and luster. If the color difference is obvious, it is not suitable for purchase.
⒋ Flatness: Check the surface of the aluminum alloy profile, there should be no dents or bulges.
⒌Gloss: Aluminum alloy doors and windows should avoid buying profiles with obvious defects such as open bubbles (white spots) and slag (black spots), cracks, burrs, and peeling on the surface.
⒍Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing, swipe lightly on the surface of the profile to see if the oxide film on the surface can be wiped off.
